GLASS-MOLDIN G MACHINE.

' To all whom it may concern."

Be it known that I, HAiiRY A. SoHNnL- BAOH, a resident of Grafton, in the county of Allegheny and State of Pennsylvania have 5 lnvented'a new and useful Improvement in Glass-Molding Machines; and I do hereby declare the following to be a full, clear, and

exact description thereof.

My -inv'ention relatesto glass molding machines, and more particularly to that type of machine in which a rotary table'travels ona suitable track, said table carrying the molds I and the molds beingbrou ht around into position to receive the mo ten glass and the blowing, or pressing, as the case may be, all being performed automatically.

The object of my invention is to provide for the sprayin of the molds with a cooling fluid after they ave been opened and the fin-- ished article removed therefrom, and dispensew'ith the-necessity of lowering the mold odily into a tank of cooling fluid, ashas.

' been the general-custom heretofore.

To these ends my mvention comprises, generally stated, in COI1]uIl0tlOI1 with a ma-' chine of this character, a rotary table uponwhich the molds are sup orted, a track upon which said table trave blow pipes supported in operative position with reference to -l.0.catedin the-possible path of said blow pipes in position to spray the molds 'as they come around inpositi'ong-after the article formed therein" has been removed, the water or other,

fcooling fluid. being supplied from a suitable tank or reservoir.. In the accompanying drawings Figure 1 is an elevation partly in section showing my in 'vention; Fig. 2 is a .cross section on the line spraying device.

Like numerals indicate like parts in each of the figures.

I have illustrated my invention in con- 'nection with a well known type of blowing "machine, and as my invention does not relate to the mechanism for operating the machine will only refer to the same generally. The

machine is mounted. upon the carriage "2, with the supportin'g wheels 3 by means of 50. whioh'it' may be conveyed from one part of the factorytto, the other. {Mounted on the -carriage 2 is the standard 4; which carries the overhanging frame' 5; A central-shaft 6 is 5 5" j'ournaled bearings inthe overhanging I Specification of Letters Patent.

"described, acts .to rotate the table 8 having is to feed the molten glass to the molds as said molds, and a movable spraying device.

frame 5 I to the carriage 2. This shaft is driven by the motor 7 which is connected u by suitable mechanism with said shaft. This shaft, through-mechanism which need not be the wheels 9 which travelupon the track 10. This table 8 carries the molds 11 which may be of any suitable construction, those shown being the ordinary two-part molds which are adapted to be opened and closed by the 5 power from the cylinders 12 connected u to said molds by the piston rods 13. The b ow pi es 14 are adapted to-be inserted into suitab e sockets 15 and air is conveyed to said blow pipes from a suitable'blowing engine. The lower ends .of the blow pipes 14 enga'ge the openingsof the molds 11.

The operation of the mechanism is'entircly automatic and all that the operator has to do they come around and insert the blow pipes in osition for blowing.

n the carriage 2- is the tank 16 for water or other cooling fluid. A pipe 17 leads from the tank 16 up to the pump 18 by means of which water is drawn from the tank 16 and a pipe 19 leads from the pump 18 to the point 20,- where a flexible connection 21 is connected with said pipe and to the swinging arm 22. This swinging arm 22 is swivclcd on the pipe 19. A collar 23 is secured to the pipe 19 by the set' screw 24. The swivel 25 engages the collar 23 and permits of the swinging of the arm 22 thereon.

When my invention is applied to a machine of the above character, the table 8 carrying the molds 11 travels around on the-- track 10 and after the article has been blown the mold is opened automatically and the blow pi e removed, together with the article. The mold then passes around in'position under the nozzle 26, where t-he water is sprayed onto the mold to cool the inside and outside of the mold then passin on in position to receive another charge of molten glnss. .The water being sprayed into the mold over the tank drops-back into the tank and the pump 18 o erated by the motor 7 draws the water up tl frough the return pipe 17 and discharges it again through the pipe 19 to the spraying nozzle 26. As a consequence the water is used over and over again, and as the molds do not themselves pass down into the water the water is not heated to any great extent, and as a consequence is kept in cooler condltion for spraying the molds. In casethe operator should for any reason fail to withdraw the blow-pipe, 'and said blow-pi e should travel around in position to strike t e arm 22 carrying the nozzle 26, said arm is ca able of swinging or ielding so as to vallow t e pas- .sage of the b ow-pipe and not in any way interfere with the operation of the machine.

my invention I provide for the cooling of the molds without the necessity of lowering the molds bodily into the tank of water 1 (which has been the common practice, and

,which requires that the track upon which the ""molds travel be cam-like in construction so as to carry the mold down into the water. This method of lowering the molds bodily into the water requires a greater amount of power and creates a strain on the machine,

as these molds are very heavy. Bymy m-- vention the wheels of the rotary table travel on a track all parts of which are substantially in a horizontal plane, so that the power to rotate-the table is greatly reduced, while said blow P P 1 whereby Said fluid dlscharg at the same timelthe water is kept in a cooler condition.
